[PATCH] vesafb: Drop blank hook
From: Bugzilla Bug 5351
"After resuming from S3 (suspended while in X), the LCD panel stays black .
However, the laptop is up again, and I can SSH into it from another
machine.
I can get the panel working again, when I first direct video output to the
CRT output of the laptop, and then back to LCD (done by repeatedly hitting
Fn+F5 buttons on the Toshiba, which directs output to either LCD, CRT or
TV) None of this ever happened with older kernels."
This bug is due to the recently added vesafb_blank() method in vesafb. It
works with CRT displays, but has a high incidence of problems in laptop
users. Since CRT users don't really get that much benefit from hardware
blanking, drop support for this.
